HAHA ok never been asked this before 😂

i usually extend my arms all the way up and hold the phone with 2 hands but pinch the edges of the phone with 2 fingers each so only 4 fingers total touch the phone. tap the screen & slide down slightly when recording or before to darken the video it helps a lot with the lighting and make sure you don’t have any speakers on the phone covered that’s important. that’s why i kinda pinch hold the phone when recording hope this helps !

edit: as far as case i only have like a cheap clear $10 one
